Teaching myself the guitar, am I destined to fail?

[skyelee90]

I bought myself a washburn guitar in June and I have been trying to teach myself to play since then. I know many chords such as G,A,E,Em,D,D7,C, and G7. I can play them fairly well and can change chords quickly. The problem is I have trouble playing songs. I try to practice with a metronome but i'm still having trouble with my timing. I just recently bought a book that is teaching me the notes on each string and I'm doing a little better. My question is, should I keep trying to teach myself or should I just give up and take lessons? Any tips? Essenstials? I'm afraid to take lessons because I am afraid the teacher will be impatient, plus the expenses will be hard for me to pay. Any suggestions? Thank you!
